well then check mark "use firmware control mode" alongside with "override zero fan speed mode" and see if it solves your issue
but i think your card wont support going below 20%, on your picture see those dotted lines? thats what your GPU firmware reports as minimum and maximum allowed range for custom profile
I usually don´t like to "force" things to work :/ , but wish to have zero rpm until 30ºc , the truth is that my GPU idles at 26-28ºc anyway , so the fan´s would not be off much time anyway .... my question is the fan´s always spinning like it is now will make fan´s die sooner or it will have no enough difference to worry about on the lifespan of the fans.... the temperatures on gpu seems to hit 78ºc on max (GPU die Hotspot) and 57ºc max on GPU die (edges) temperature . the temperatures are based on a full system stability test for 1h
Could you give me your opinion about the temps and the fan curve ?
current fan curve (since 0rpm is not possible I have edited a bit):
